Mine Flotation High Pressure Industrial Blowers Application

Water TreatmentAquaculturePowder and granules
Be used in water treatment plant for water purification and sediment mixingBe used in a variety of fish pond for oxygen supply and mixing, and also for aquariums and live fish tankPowder or granules
(such as plastic materials, etc.) can be transported by pressure or vacuum
IncineratorBallast pumpSandblast
Air combustion and exhaust emissionsUsed for chemical liquid unloading and other ballast pumpsUsed as air source for blast jet
BoosterCompost fermentationCereals Transportation
Used for high-pressure exhaust to make the gas into tiny moleculesHigh-pressure air take into the livestock manure tank to increase contact area of livestock manure and air , also apply to sewage treatmentCereals such as wheat are transported from the rotary pilot valve with air
Pipe clearingSaunaPlating Bath
Used to remove dirt and iron dust during pipeline replacement or overhaulUsed for the sauna to provide air bubbles, mainly used for hospitals, hotels and etc.Use air to stir the electrolyte to keep the electrolyte circulation, and disperse the attached blister to make plating quickly, spread evenly
Produce line dryingCar wash drySmoke exhaust
Quickly remove the water or oil on the cleaned itemsDry the car after washingExhaust smoke quickly to reduce pollution
Stripping from moldAir cushion of
Cut off machine
Dry air knife
Easy to remove the finished product after stampingIncrease buoyancy, easy to moveUse the blower to blow off the tiny dust and water droplets on the circuit board

Description of Performance parameters

The performance parameters table shows the model, outlet diameter, rotate speed, discharge pressure, air capacity and power of motor.

1. The air capacity and pressure in the tables is in standard suction state. The standard suction state is 20ºC temperature, 1.033 kgf/cm2(101.3Kpa) Standard atmospheric pressure and 65% relative humidity.

2. The air capacity and pressure range of some blower models is repeated, to ensure the service life and low noise, should use the larger model.
